[摘要] 四川省江油市太白碑林太白樓為鋼筋混凝土仿古建筑，汶川“5·12”大地震使其層3全部混凝土柱(28根)破壞。因采用置換法加固，設(shè)計(jì)一個(gè)20. 9m高的卸荷鋼框架暫時(shí)將層3以上部分托起，待置換灌漿料達(dá)到設(shè)計(jì)強(qiáng)度后再將其放下。重點(diǎn)介紹了在卸荷鋼框架的設(shè)計(jì)中如何考慮仿古建筑結(jié)構(gòu)的特點(diǎn)及托換過(guò)程中余震的影響，為加固卸荷積累了經(jīng)驗(yàn)。

Abstract: Taibai Steles' Taibai Building in Jiangyou city, Sichuan province, is a reinforced concrete antique building. All of 28 concrete columns in the third storey were damaged. In order to dismantle and replace the damaged columns, the method of the replacing grounting materials was adopted. So a 20.9m high decompression steel-frame should be designed to jack up the part above the third storey, after the replacing grounting materials reached the design strength then put them down the part above the tlurd storey. How to deal with the features of the antique building structure during the design of decompression steel-frame and the aftershocks' influences in the course of upbearing and replacement were focused on. It accumulates experiences for decompression of antique building.
